The nurse is caring for a client with a suspected myocardial infarction. Which laboratory value is most specific for confirming the diagnosis?
- A. Troponin I
- B. Creatine kinase (CK)
- C. Myoglobin
- D. Lactic dehydrogenase (LDH)
Correct Answer: A
Rationale: Troponin I is the most specific marker for myocardial infarction, rising within hours and staying elevated for days CK and myoglobin are less specific, LDH is outdated. Nurses monitor this, correlating with ECG and symptoms, aiding rapid diagnosis and treatment.
Refers to the pressure when the ventricles are at rest
- A. Diastole
- B. Systole
- C. Preload
- D. Pulse pressure
Correct Answer: A
Rationale: Diastolic pressure is when ventricles rest e.g., 80 in 120/80 showing resistance. Systole (contraction), preload (filling), pulse pressure (difference) differ. Nurses measure this e.g., hypertension for health, per BP definitions.

Considered as Safest and most non invasive method of temperature taking
- A. Oral
- B. Rectal
- C. Tympanic
- D. Axillary
Correct Answer: D
Rationale: Axillary temp is safest, least invasive no mucosal entry e.g., armpit avoids rectal (perforation), oral (biting), or tympanic (ear) risks. Ideal for infants, nurses use it e.g., frail patients for safety, per non-invasive guidelines.
